表面固定和溶液分散的量子点（QDs）与具有不同等电点的蛋白质的相互作用，特别是与QDs的分子结合能力和蛋白质的团聚进行检查，表明静电吸引的性质。阐明了涉及蛋白质表面电荷分布和蛋白质分子大小的机制。
Interactions of surface-immobilized and solution-dispersed quantum dots (QDs) with proteins possessing different isoelectric points, particularly the molecular binding capability and agglomeration of proteins with QDs are examined, indicating an electrostatic attraction nature. A mechanism involving protein surface charge distribution and protein molecular size is elucidated.
